For a person of ordinary skill in the art, specific meanings of the foregoing terms in the present utility model may be understood according to a specific situation.

In an embodiment of the present utility model, as shown in FIGS. 1 to 6, a storage box is provided, and is suitable for storing food, articles, and the like. Specifically, the storage box may be an iron box, a plastic box, or the like, and a material thereof is not limited. More specifically, the storage box comprises a bottom case 10 and an upper cover 20, and a first side of the upper cover 20 is rotatably connected to a first side of the bottom case 10. Similar to a storage box in the prior art, the first side of the upper cover 20 and the first side of the bottom case 10 may be penetrated by using a long axis, so that the upper cover 20 and the bottom case 10 are rotatably connected, or may be rotatably connected in another way.

Further, as shown in FIG. 4, an inner flange 221 is arranged on a second side of the upper cover 20, and a lock piece 30 is connected to an inner end of a second side of the bottom case 10. As shown in FIG. 3, the lock piece 30 comprises a raised snap 321 and an unlocking column 311 that protrude beyond the second side of the bottom case 10, and the raised snap 321 is located above the unlocking column 311.

Further, when the upper cover 20 covers the bottom case 10, the raised snap 321 is snap fit to the inner flange 221, and pressing the unlocking column 311 can force the raised snap 321 to detach from the snap fitting to the inner flange 221.

When the storage box provided in this embodiment of the present utility model is in use, the upper cover 20 covers the bottom case 10, and the upper cover 20 is connected to the bottom case 10 by snap fitting the raised snap 321 connected to the bottom case 10 to the inner flange 221 of the upper cover 20, thereby locking the storage box. When the storage box needs to be opened, only the unlocking column 311 of the lock piece 30 connected to the bottom case 10 needs to be pressed, and the unlocking column 311 drives the lock piece 30 to move inward, so that the raised snap 321 on the lock piece 30 is forced to move inward, and the raised snap 321 is detached from the snap fitting to the inner flange 221, thereby opening the storage box. The operation is convenient, and even if the storage box is frequently opened for use, the locking of the storage box can still be kept stable and effective, and the storage box is not easy to automatically open with high practicability.

In another embodiment of the present utility model, as shown in FIGS. 2 and 5, the bottom case 10 comprises a bottom plate 11, a lower outer frame 12 arranged around the circumference of the bottom plate 11 and protruding upward, and a lower inner frame 13 bent inward at the top end of the lower outer frame 12 and protruding upward. Specifically, the bottom plate 11, the lower outer frame 12, and the lower inner frame 13 are preferably formed integrally. The lower outer frame 12 and the lower inner frame 13 jointly form a frame with a certain height, and enclose with the bottom plate 11 to form an accommodating cavity for accommodating food or articles.

Further, as shown in FIGS. 2 and 3, the lock piece 30 is connected to an inner side of the lower outer frame 12, the lower outer frame 12 is provided with a column hole 121 for the unlocking column 311 to pass through and protrude beyond the bottom case 10, the diameter of the column hole 121 is slightly greater than the outer diameter of the unlocking column 311, the lower inner frame 13 is provided with a snap hole 131 for the raised snap 321 to pass through and protrude beyond the bottom case 10, and the hole area of the snap hole 131 is greater than the cross-sectional area of the raised snap 321. That is, the column hole 121 and the snap hole 131 are respectively used to avoid the unlocking column 311 and the raised snap 321, so that the unlocking column 311 and the raised snap 321 protrude beyond the case, the protrusion of the unlocking column 311 is used for a user to press, and the protrusion of the raised snap 321 is used to snap fit with the inner flange 221, thereby implementing locking between the bottom case 10 and the upper cover 20.

Still further, as shown in FIGS. 2 and 4, the upper cover 20 comprises an upper plate 21 and an upper outer frame 22 arranged around the circumference of the upper plate 21 and protruding downward, the inner flange 221 is arranged at the bottom end of the upper outer frame 22, the upper outer frame 22 covers the lower inner frame 13, and a first side of the upper outer frame 22 is rotatably connected to a first side of the connection between the lower outer frame 12 and the lower inner frame 13. Specifically, the upper plate 21 and the upper outer frame 22 are preferably formed integrally. The inner flange 221 is preferably formed by buckling or bending at the bottom end of the upper outer frame 22. Relative rotation of the upper outer frame 22 may allow to open the opening size between the upper cover 20 and the bottom case 10 to be opened.

In this embodiment, the upper cover 20 and the bottom case 10 are approximately similar in appearance, and may be in a circular shape, a square shape, or another shape.

In another embodiment of the present utility model, as shown in FIGS. 2, 3, and 6, the lock piece 30 comprises a horizontal plate portion 31 and at least one vertical plate portion 32, where the horizontal plate portion 31 is a horizontally arranged component, and the vertical plate portion 32 is a vertically arranged component. Each vertical plate portion 32 is vertically connected to the horizontal plate portion 31, and the raised snap 321 is arranged at the end of each vertical plate portion 32. The unlocking column 311 is arranged on the horizontal plate portion 31, the unlocking column 311 is preferably directly opposite to the raised snap 321, and the horizontal plate portion 31 is connected to the inner wall of the lower outer frame 12. In this way, when the unlocking column 311 is pressed, the unlocking column 311 drives the horizontal plate portion 31 to move inward. In this case, the vertical plate portion 32 connected to the horizontal plate portion 31 also moves inward, and the raised snap 321 on the vertical plate portion 32 also moves inward. Thus, the raised snap 321 may be forced to release the snap-fit with the inner flange 221. The operation is very convenient, and the snap-fit does not automatically unlock.

In another embodiment of the present utility model, as shown in FIGS. 2 and 6, two vertical plate portions 32 are arranged, the two vertical plate portions 32 are arranged adjacent to opposite ends of the horizontal plate portion 31 respectively, two unlocking columns 311 are arranged, and the positions of the two unlocking columns 311 are directly opposite to the positions of the two vertical plate portions 32 respectively. Specifically, with the arranged two unlocking columns 311 and two raised snaps 321, it can be ensured that only by pressing the two unlocking columns 311 at the same time, can the two raised snaps 321 be released from the snap-fit with the inner flange 221. In this way, locking stability of the storage box is better, the snap-fit is not released easily under a general external force, and the structural design is very clever.

In another embodiment of the present utility model, as shown in FIGS. 1 and 2, a first through-hole 122 is provided on the lower outer frame 12, a second through-hole 312 directly opposite to the first through-hole 122 is provided on the horizontal plate portion 31, and the horizontal plate portion 31 is connected to the lower outer frame 12 via a riveting column 50 sequentially running through the first through-hole 122 and the second through-hole 312. Specifically, the riveting column 50 may connect the horizontal plate portion 31 to the lower outer frame 12 together, and they are easily assembled via through-holes. Compared with a glue bonding method, this connection method does not cause the lock piece 30 to detach from the connection to the bottom case 10 even in frequent use.

In another embodiment of the present utility model, as shown in FIGS. 2 and 3, a pressing piece 40 is arranged inside the horizontal plate portion 31, the pressing piece 40 is provided with a third through-hole 41 directly opposite to the second through-hole 312, and the riveting column 50 connects the lower outer frame 12, the horizontal plate portion 31, and the pressing piece 40 after sequentially running through the first through-hole 122, the second through-hole 312, and the third through-hole 41. Specifically, the pressing piece 40 is added to press against the lock piece 30, so that the lock piece 30 is prevented from releasing the connection to the riveting column 50 in frequent use, ensuring a more stable connection between the lock piece 30 and the bottom case 10.

In another embodiment of the present utility model, as shown in FIG. 3, the horizontal plate portion 31 does not fall into an orthographic projection of the lower inner frame 13. In this way, the horizontal plate portion 31 may be hidden in a step formed between the lower outer frame 12 and the lower inner frame 13, and when the upper cover 20 is opened, it is not easy to discover the lock piece 30, providing a certain anti-disassembling function.

In another embodiment of the present utility model, as shown in FIGS. 2 and 6, the raised snap 321 is a wedge block with a bevel arranged upward. Specifically, the wedge block has a bevel, and it is easier to snap fit with the inner flange 221 by using the bevel, so as to facilitate locking of the storage box.

In another embodiment of the present utility model, as shown in FIG. 6, the lock piece 30 is integrally injection molded by using a plastic material. The lock piece 30 integrally injection molded by using a plastic material has certain elasticity. In this way, the horizontal plate portion 31 arranged thereon has certain elasticity. When the unlocking column 311 is pressed, once an external force is removed, it is easy to recover to the original state, and frequent use can still ensure performance of the lock piece.

In another embodiment of the present utility model, as shown in FIG. 2, a sealing gasket 60 is arranged on the top of the upper cover 20. The sealing gasket 60 may be arranged to improve sealing performance of the inner cavity of the storage box. When the storage box stores food, moisture protection may be implemented to some extent.

The foregoing description provides merely preferred embodiments of the present utility model, but is not intended to limit the present utility model. Any modification, equivalent replacement, and improvement made without departing from the spirit and principle of the present utility model shall fall within the protection scope of the present utility model.
